Answer:
Explanation:
The empirical formula is the simplest whole-number ratio of the elements in a compound to one another. To find the empirical formula given a molecular formula, divide all the subscripts by their greatest common factor.
3, 12, and 6 can all be divided by 3, which makes the empirical formula
Answer:
- <u>414K</u>
Explanation:
The question is not completely clear because some missing parts or grammar (syntax) errors.
Interpreting it, the question is <em>what is the Kelvin temperatue of the air in a tire, when the pressure in the tire has increased to 225 kPa, if the initial conditions of the air inside the tire were 188kPa of pressure and a temperature of 32ºC.</em>
To solve this, you can assume constant volume and use the law of Gay-Lussac for ideal gases:
That equation works with absolute temperatures, i.e. Kelvin.
- 32ºC = 32 + 273.15 K = 305.15K
Then solve for T₂, substitute and compute:
